Primary and secondary aims and hypotheses for Airman’s Edge P2P program.

Aim 1: To Test the Efficacy of a P2P Program for the Reduction of Suicidal Behavior among Military Personnel.
Hypothesis 1a: Military personnel randomized to the P2P condition will be significantly less likely to make a suicide attempt and will report significant reductions in suicide ideation during follow-up as compared to military personnel randomized to the control condition.
Hypothesis 1b: Squadrons randomized to the P2P condition will have significantly lower rates of suicidal behavior and suicide ideation as compared to squadrons randomized to the control condition.
Hypothesis 1c: Installation-level suicide rates will decelerate over time as the P2P program is implemented.
Aim 2: To identify moderators and mediators of the P2P program’s effects on suicidal behavior.
Hypothesis 2a: Military personnel randomized to the P2P condition will report larger improvements in emotion dysregulation and cognitive rigidity, meaning in life, and social support as compared to personnel randomized to the control condition.
Hypothesis 2b: Squadrons randomized to the P2P condition will report larger improvements in emotion dysregulation and cognitive rigidity, meaning in life, and social support as compared to squadrons randomized to the control condition.
